CHARLES L. HENDERSON, OF NEENAH, WISCONSIN, ASSIGNOR TO PAPER PATENTS COMPANY, OF NEENAH, WISCONSIN, A CORPORATION OF WISCONSIN.

SECTIONAL PAPER-MACHINE DRIVE.

Application filed December 20, 192Gv This invention relates to sectional paper n'iaclsine drives, and more particularly to drives .hicli are adapted to use in connection with paper 'zaachinerzi, to enable correlation of the speed of various sections of such imichines to be more easily and accurately accomplished.

The objects of the invention are to provide an ellieiont mechanical drive of the class described; to provide a d rive which is capable of effecting accurate :nljusi'in'ient or variation of the driven speed; to provide means which will be compact and will conscqi'iently roquire a mii'iiniuni of floor space; to provide such means, of which a. plurality may be simultaneously driven from a. common power shaft, and each of which will be independent 1v adj l'istable so as to control. the respective sections of a, machine to which they are con-- nceted; and further to provide a mechanical drive of the class described, of which a plurality may be driven from a. connnon power shaft, and which may be compactly arranged relative thereto, and in general, to provide an improved drive for paper machines.

(Ether objects and advai itagcs of the invention will be umlersl'ood by reference to the 'i i' llowing slweilication when considered in connecii in. with the accompanying drawings, illustrating a. selected, embodiment of my inzention, and in which:

Fig. 1 is a, plan section.

Fig. 2 is a side elevation partly in section, and

Fig. 3 is an end elevation of the left-hand end 5's Fig. 1.

Referring now to the i'lrawings, I have in dieated at a, power or drive shaft, which may, for the moment, be considered to be a long shaft extending substantially the entire lr gth of paper machine, and from which shaft the various sections of a paper machine such as the couch, the presses, driers, and the calender may be driven.

According to the present invention, the

shaft 10 is journaled in suitable bearings 11 on the base member 12, which base member is adapted to support mechanism for transferring power from the shaft 10 to one of the sections of a paper machine.

A driven shaft is indicated at 13 and is adapted to be directly connected to a roll or other driven element of one of the sections of the paper machine. The shaft 13 is journaled in suitable bearings 14, which are sup- Serial No. 155,995.

ported in suitable seats 15 in a bushing 16, which bushing is supported in the housing 17. The inner end of the shaft 13 is provided with an enlargement 18 on which is seated an internal gear member 19, which is provided with an internal ring gear 20. The member 19 is keyed to the enlarged end 18 as at 21, so as to rotate therewith.

The internal ring gear 20 is a part of a. planetary gear mechanism which includes in addition to the ring gear, a plurality of pinion gears 21 and a sun gear 22. The sun gear is keyed as at to the inner end of a shaft 2a, which isjournaled in suitable bearings 25 in a bearing sleeve 26, which is supported in a seat 27 provided in the housing 17 for that purpose. The inner end of the shaft 24: is provided with a reduced extension 64, which supported by means of a suitable hearing such as a roller bearing indicated at (S5 in the recess 66, in the enlarged end 18 of the driven shaft 13.

To the outer end of the shaft 24, a bevel gearmembertZS is fastened, and this bevel gear n'ieinber is provided with a removably mounted bevel ring gear 29. The gear 29 meshes with another bevel gear 30, which is keyed to a sleewe. 31 by means of a key and the sleeve 3i is disposed about said driving shaft 10 and is journalcd in suitable bearings 32, which are supported by cap members 33. The cap members 33 are mounted in seats 34-providcd in the housing 17. It will be noted that the sleeve 31 is rotatably journaled in bearings 32, whereby excessive friction and wear on the shaft 10 is avoided, since the sleeve does not bear directly on the shaft. The sleeve 31 is provided at its left-hand end (Fig. 1) with a clutch member 35, which is keyed thereto by means of a key 36. The

clutch member 35 is adapted to be engaged by another member 37, which is keyed to the drive shaft 10, so as to rotate therewith, but is slidable axially thereof. The clutch member 37 is provided with a groove 38, which is adapted to be engaged by a suitable collar for elfectin engagement or disengagement of the clutch in a well known manner, and which mechanism is not illustrated in the drawings, since it is believed to be well known and mulerstood by those skilled in the art. The clutcl is preferably of the magnetic type, although it may be of any other desirable type of friction or positive clutch.

When the clutch members 35 and 37 are shaft 10 may be driven from another shaft running parallel thereto.

The arrangement above described results in a compact unit which affords effective and accurate control of the driven shaft 18 and mechanism connected thereto. By means of the unit construction, I am able to quickly substitute a new nnit for an old. one which has become defective, whereby tie-ups of such machines as paper machines for a long period of time may be averted.

I am aware that changes in the arrangement and construction of parts may be readily made without departing rom the spirit of the invention as defined by the following claims, which should be construed as broadly as possible consistent with the state of the art.
